In the Science Museum in London, there is a 22.45-m-long pendulum (known as Foucault's pendulum). It swings, without stopping, in one of the stairwells.
(1) i** Calculate the time period of the pendulum. (Take g=9.81 Nkg−1 )
(2) ii** If the pendulum were to be taken to the surface of the moon, where the value of gravitational field strength is 61 of that of the Earth, what would its time period be?
